HAT-PRESS.

Application filed January 18, 1912.

To all whom it may concern.

Be it known that I, JOSEPH F. SENN, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented an Improvement in Hat-Presses, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

This invention relates to that class of presses in which a hat die, held in a steam heated die-holder, is brought up to its flexible mate, thereafter, the hat receiving the necessary pressure to form it as desired.

The invention has for its object a machine designed to carry out a novel method of operating the die holder which is accomplished entirely by means of water pressure.

The invention also has for its object to construct a machine whereby the flow of the water used for operating the ram may be caused to cool the necessary packing ring around said ram.

A further object of the invention is to provide a telescopic or extensible steam connection bet-ween the steam heated die holder and the usual supply pipes.

lVith these and other objects in view, as will more fully hereinafter appear, the invention consists in the novel construction and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings and particularly pointed out in the appended claim, it being understood that various changes in form, proportion, sizes and minor details of structure may be made without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawings,

Figure 1 is a front elevation,

Fig. 2 is a side elevation,

Fig. 3 is a vertical section of the lower part of the press,

Fig. 4 is a plan view on line 4-4 of Fig. 3,

Fig. 5 is a section of the flexible part of die at the top of the press,

Fig. 6 is a plan view of the top,

Fig. 7 is a fragmental plan similar to Fig. 4. showing a changed position of parts,

Fig. 8 is a detail of the ram,

Fig. 9 is a detail of the steam connection.

A suitable frame is provided, comprising a basel, a cap or top casting 2, between which are mounted the strain or guide rods 3, upon which is carried the die holder 4 containi a d e B am in do ted lin s Specification of Letters Patent.

Serial No- 672,018.

In operating, a 3-way valve, 5 is opened, admitting water pressure from the supply pipe (5 to pass through into pipe 7, which is connected to the ram chamber, forcing the die f, containing the hat to be pressed against the lower side of the flexible die 4 Before pressure is admitted into the chamber 4 above the flexible die i by means of the valve 9, it isdesirable to distribute the expected load therefrom to the strain rods 4; through the frame. Therefore a disk 10 is suitably mounted on the base 1, adapted to be revolved or rotated by a foot lever 11, through a chain and rod connection 12 and 13, until it assumes a position whereby a set of holes 10 out of which the legs 10, depending from and traveling upwardly with the die holder 4-,are withdrawn, will be replaced by the solid portion 14 adjacent to said holes 10.

The legs 10 are then caused to rest on surfaces 14 by permitting a quantity of water to escape through the pipe 7, by operating the valve 5 into the pipe 7 When the press is in the position described, that is, the lower die raised as shown in Fig. 2, and pressure present within the flexible die chamber 1 (Fig. 5), the hat or other work between said dies is being heated by steam which is introduced into the space 4 through the circulating pipes 15.

The next step is to release the pressure in the chamber 1; first, however, the valve 9 is to be closed, cutting off the pressure present in pipe 6, the valve 16 in pipe 17 is opened and allows a sufficient amount of water to escape, relieving the pressure in said chamber 1.

Again the valve 5 is operated to cause the water pressure to raise the die holder as before described but this time, however, only far enough to allow the legs 10 to clear the plate 10, which will be brought back by the action of the tension spring 18, to its normal position, permitting the holes 10 to assume a position exactly under and in line with the legs 10", said position and rotation being predetermined or controlled by a stop, comprising bolts 19 fixed to the base or frame and notches 20 in plate 10.

To lower the die holder 4., it is only necessary to operate the valve 5 so that the water in ram chamber 8 will have free egress through pipes 7 ,7 thence to Waste, through pipe 17.

W the j ct n iew at attaining e maximum speed in operating, the die is allowed to drop, responding to its own weight, which is considerable, and to preclude the possibility of damaging the base or die holder, by such impact, a cushioning spring 21 is provided of such length and resistance as best adapted to serve its purpose.

To minimize the radiation of the heat necessarily introduced under the lower die, there is provided an insulating sheet 22 of non-conducting material interposed between the lower horizontal members of the die holder, said die holder comprising two members substantially dish shaped in cross section, adapted to fit one into the other, both having sloping sides fitting closely together at their top, the inner member being sloped inwardly considerably more than the outer one, thus forming in the intervening space an insulation of dead air.

Fig. 8 more clearly shows the construction of the ram with its necessary packing ring 23, where a certain amount of heat is unavoidably conducted and to preserve said packing ring from injury thereby, the metal adjacent thereto is cooled by the How of water used to operate the ram.

This is accomplished by constructing the lower portion of the ram of a suitable length of pipe or tubing, incasing an upwardly eX- tending pipe 7, the latter terminating substantially on a level with the packing ring 23.

The steam connections to die holder 4 are brought through the base 1 at convenient points, and breferably extend upward along either side of the ram, as shown in Fig. 3.

Fig. 9 clearly illustrates the method of securing the vertical portion of pipe 15, which is passed through a larger pipe 24 constituting a spacer which is held between the frame 1 and a nut 25, locked in position by a locknut 26, said nuts holding against a running thread at the lower end 27 of pipe 15. To the upper end 28 is secured a coupling 29, which in turn supports a nipple 30, there being connected thereto a packing gland 31 forming a steam tight joint through which Copies of this patent may be obtained for five cents each, by addressing the Commissioner-of Patents, I

a sliding or reciprocating section of pipe 15 may pass, completing the connection to the steam space i In the usual type of press of this class, the flexible die depends from a fiat member or disk, substantially on a line with the point of juncture of the two members forming the pressure chamber; in Fig. 5, is clearly shown an arched or dome shaped member, 32 of such shape and size, as to allow of a wide variance in the shape or contour of the upper surface of the die 4, permitting the relatively low surfaces thereof to enter the dome thereby, equalizing the pressure on the entire surface.

It is occasionally necessary to remove the die from the holder 4. For this purpose there are provided holes through the bottom of holder 4, wherein rods may be inserted when holder i and die 4t are in a raised position, thereupon holder l being lowered will clear itself from die r when same may be removed or replaced.

Having now described my invention, what I claim as new. and desire to secure by Let-- ters Patent is:

In a. hat-pressing machine, a b d h i openings, a reciprocatory die holder having an internal space to hold a heating medium,

a supply pipe for said heating medium, opening into said space said supply pipe being in telescoping sections, stems extending from the die holder, a rotatable plate mounted on the bed and having openings which are adapted to register with the openings in the bed, through which registering openings the aforesaid stems pass, and said plate also having elongated openings through which theaforesaid supply pipe passes, and means for rotating the plate when the stems clear the openings thereof.

In testimony that I claim the foregoing as my invention, I have hereto subscribed my name before two witnesses. V V
